Not a bug per se, but if you side with Lynine in the first part of the Sylvan Forests when you visit Orilise she says:

It would be kind of neat if the game tracked (presumably it does) which is your ally in that phase and the text would change to something like:
"In our brief contact during this crisis, I didn't have the chance to learn your name."
I suspect that if you side with Orilise first and Lynine second there is a similar issue but I haven't checked it yet.
